A CIA man, home from an assignment in Iraq, is given a cake duty, working security at a safe house. When he reports for duty, he walks into a massacre in progress. After rescuing a woman, and going deep undercover, he finds that, one by one, his contacts and friends are being killed. When he finds out why, the trail leads to a very unexpected place.

This is a real page turner, arguably, Coonts' best work.
